Welcome to the SeeMeCNC Community

I am just wondering. Can a brass fitting be used in place of the PEEK insulator, I would use a fan to keep the brass cool. I know the PEEK insulator is there to keep that area cool so as not to prematurely melt the plastic filaments. But am wondering if this alternative would work. I would install a fan to keep the brass cool.

And I hucking lost my nozzle! Darn it! Now I have to wait for a new one.

Sorry for your loss. I'm going with no, brass won't work. The main purpose of the peek is to limit the length of the melt zone. Brass would conduct the heat far to much and you would be melting up into the nozzle. I do not think a fan would be of much help.

Thanks Foshon, That avatar of yours was the expression on my face when I found PEEK had cracked.

Your peek is cracked!? Go to the doctor right away! LOL

On a more serious note, that sucks dude. I know how you feel though, they are only 9 bucks, but the wait is what sucks. I'd order a few extras to keep in your personal stock. That's what I'm doing.

On a suggested hack it together for now direction.

Have you considered removing it, using a vice to sqeeze it gently together and take a blow torch and carefully remelt the crack back together? You will have to limit your temps to be lower than stock but it might get you by until the new one arrives.

Is the Peek on the Seemecnc Hot Ends replaceable?

yes they sell replacements... it just screws out from what i'm told. http://shop.seemecnc.com/PEEK-Insulator ... -71553.htm

Piece left behind in brass nozzle was damn near impossible to remove. I was thinking of doing the same. Thanks for the tip.
